STEP 14. Check the symptoms.
Q: Do the radiator fan and condenser fan operate correctly?
YES: The procedure is complete.
NO: Return to Step 1 .
INSPECTION PROCEDURE 4: Radiator Fan and Condenser Fan do not Change Speed or Stop Radiator Fan and Condenser Fan Drive Circuit Refer to INSPECTION PROCEDURE 3: RADIATOR FAN AND CONDENSER FAN DO NOT OPERATE
.
CIRCUIT OPERATION
The fan control module is powered from fusible link number 2. The PCM judges the required revolution speed of radiator fan motor and
condenser fan motor using the input signals transmitted from A/C switch,
automatic compressor controller, vehicle speed sensor and engine coolant
temperature sensor. The PCM activates the fan control module to drive the
radiator fan motor and condenser fan motor.
TECHNICAL DESCRIPTION The fan controller has variable control of the radiator fan motor and the condenser
fan motor speeds using signals transmitted from the PCM. TROUBLESHOOTING HINTS NOTE: If the engine coolant temperature reaches 110°C (230°F) or
higher, the radiator fan control runs the radiator fan for up
to 5 minutes even after the ignition switch is turned to the
"LOCK" (OFF) position [the fan stops its rotation when the
engine coolant temperature decreases to 110°C (230° F) or
lower.]

NO: Replace the radiator fan motor. Then go to Step 7.
STEP 7. Check the symptoms.
Q: Do the radiator fan and condenser fan operate correctly?
YES: The procedure is complete.
NO: Return to Step 1 .
INSPECTION PROCEDURE 5: Radiator Fan does not Operate TECHNICAL DESCRIPTION The cause could be a malfunction of the radiator fan motor or an open circuit
between the fan control module and the radiator fan motor. TROUBLESHOOTING HINTS Malfunction of radiator fan motor DIAGNOSIS Replace the radiator fan motor. INSPECTION PROCEDURE 6: Condenser Fan does not Operate Radiator Fan and Condenser Fan Drive Circuit Refer to INSPECTION PROCEDURE 3: RADIATOR FAN AND CONDENSER FAN DO NOT OPERATE

3. Set up a timing light.
4. Start the engine and run it at idle.
5. Check that the idle speed is approximately 680 r/min.
6. Select scan tool MB991958 actuator test "item number 17".
7. Check that basic ignition timing is within the standard value.
Standard value: 5° BTDC +/-3°
8. If the basic ignition timing is not within the standard value, check the
following items:
Diagnostic output Timing belt cover and crankshaft position sensor installation conditions Crankshaft sensing blade condition
9. Press the clear key on scan tool MB991958 (select forced drive stop mode),
and cancel the actuator test.
10. Check that the actual ignition timing is at the standard value.
Standard value: Approximately 10° BTDC
CURB IDLE SPEED CHECK Required Special Tool:
CAUTION: If the actuator test is not canceled, the forced
drive will continue for 27 minutes. Driving in this
state could lead to engine failure.
NOTE: Ignition timing fluctuates about+/-7° Before T op Dead
Center, even under normal operating condition.
NOTE: It is automatically further advanced by about 5° to 10°
Before Top Dead Center at higher altitudes.
